・Design concept
It is a lifelike architecture that celebrates the relationship between the sea, the land and this place that has been a gate for international exchange since ancient times. The aim was to create a lively environment that blends the outdoor expanse of multiple slab strips with an indoor event space. The direction of the obliquely coiled strip relative to the site is synchronized with the topographical wrinkle that runs diagonally through the Kansai region, and is generally consistent with the direction of the steady winds that flow into the Yodogawa River system. Thus, connected to the earth as a geographic life form, the architecture will be a memory of the future, clad in the energy of wind, water, and light.
